This newly-recognised gallinule may have survived until as late as 1937, but undoubtedly became Extinct soon after. It likely disappeared as a result of over-hunting and predation by invasive rats and cats.

Porphyrio paepae was known from Hiva Oa and Tahuata on the Marquesas Islands (French Polynesia). It may have survived as late as 1937, but must have become extinct soon afterwards (Steadman 1988, Hume and Walters 2012).
